Raising 2,000 generations of bacteria may have solved this great debate in biology

Since the dawn of genetics in the early 20th century, biologists have debated if evolution is more driven by random mutations or by the original diversity in the gene pool. Having many genetic alternatives to choose from can make natural selection much faster in the beginning, but do the genetic mutations that occur over time …

Researchers are discovering mechanisms that link mutations in the “dark matter” of the genome to cancer

For many years, the human genome was seen as a book of life where parts of great eloquence and economy of expression were mixed with large stretches of laughter. The readable sections contained the code for making cellular proteins; the other regions, which represented about 90% of the entire genome, were dismissed as “junk DNA”, …
